Teamwork and its impact on chronic disease clinical outcomes in primary care: a systematic review and meta-analysis

Teamwork positively affects staff performance and patient outcomes in chronic disease management. However, there is limited research on the impact of specific team components on clinical outcomes. This review aims to explore the impact of teamwork components on key clinical outcomes of chronic diseases in primary care.Systematic review and meta-analysis.This systematic review and meta-analysis conducted searching EMBASE, PubMed, Cochrane Central Register of Controlled Trials. Studies included must have at least one teamwork component, conducted in primary care for selected chronic diseases, and report an impact of teamwork on clinical outcomes. Mean differences and 95% confidence intervals were used to determine pooled effects of intervention.A total of 54 studies from 1988 to 2021 were reviewed. Shared decision-making, roles sharing, and leadership were missing in most studies. Team-based intervention showed a reduction in mean systolic blood pressure (MD = 5.88, 95% CI 3.29-8.46, P= <0.001, I2 = 95%), diastolic blood pressure (MD = 3.23, 95% CI 1.53 to 4.92, P = <0.001, I2 = 94%), and HbA1C (MD = 0.38, 95% CI 0.21 to 0.54, P = <0.001, I2 = 58%). More team components led to better SBP and DBP outcomes, while individual team components have no impact on HbA1C. Fewer studies limit analysis of cholesterol levels, hospitalizations, emergency visits and chronic obstructive pulmonary disease-related outcomes.Team-based interventions improve outcomes for chronic diseases, but more research is needed on managing cholesterol, hospitalizations, and chronic obstructive pulmonary disease. Studies with 4-5 team components were more effective in reducing systolic blood pressure and diastolic blood pressure. Heterogeneity should be considered, and additional research is needed to optimize interventions for specific patient populations.
